TELESCOPE-MQUNTING FOR FIREARMS.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed December 18, 1913. Serial No. 807,428.

To all whom it ma concern Be it known t at I, EUGENE P. CAMUS, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Telescope-Mounting for Firearms, of which the following is a full, clear, and exact description.

My invention relates to improvementsin telescope mountings used in connection w th firearms, and the object thereof is to provlde a simple, strong and adjustable mounting which can be easily and quickly connected or disconnected from the member carrying the mounting without any tool, which connection is not affected by the vibration set up by the discharge of the firearm, and which mounting affords a perfect lateraLadjustment of the telescope thereonwithout any additional support for the telescope on the means carrying the same. I attain the above object by providing a base having automatic locking means for connecting the said base to the firearm, and which base is provided with a telescope support, and cooperating means connecting the base and support whereby said support 1s adapted to swing laterally on the base in an arc of predetermined curvature.

The invention relates to the constructlon and combination of parts to be more fully described hereinafter and fully set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of th s specification, in which like characters indicate corresponding parts in all the vlews and m which:

Figure 1 is a side elevation of a firearm provided with a telescope mounting embodying my invention; Fig. 2 is a front elevation of the mounting, partly in section, showing the details of construction; Flg. 3 is a vertical section on line 33, Fig. 2; Fig. 4 is a horizontal section on line 4 4, Fig. 3; Fig. 5 is an enlarged sectional vlew of the locking end of the base, showmg the said locking means in normal position; and Fig. 6 is a similar view showing the sand locking means in released posltlon.

Referring to the drawings, 7 represents the breech of a gun on which is provided a transverse member 8, preferably integral therewith, the ends of which are under cut by grooves 9 parallel with the axis of the breech. Removably secured to the said member 8 is a telescope mounting 10 formed of two parts, a base 11 and a telescope sup port 12. The base 11 at its bottom is provided with a recess 13 adapted to engage the member 8. Locking members 14 are pro vided at each side of the base 11 adjacent the bottom thereof, and a part of said look ing members, which are in the shape of rollers, project into the said recess 13. The projecting ends of each of the locking rollers 14 are formed into a cam portion 15 engaged in a groove 16 provided in the side extension 17 of the resilient member 18 secured to the base 11. The tendency of the resilient member 18 is to move its unsecured end, Where the extensions are provided, away from the base, thus tending to rotate the locking rollers 14 in the base in virtue of the eccentric position of the cam portion 15 on the locking roller 14 engaging the groove 16 of the resilient member.

To permit the engagement and the disengagement of the base 11 with the member 8, the lateral portion of the locking rollers 14 has a flattened portion 19 which is so related to the cam portion 15 of the roller and to the groove 16 that when the flexible members 18 are forced toward the base, the said locking rollers 14 are rotated in a direction indicated by the arrow in Fig. 5, bringing the flattened portion to the position shown in Fig. 6, thereby clearing the ends of the member 8. By releasing the resilient member 18, the said locking rollers are brought to their normal position, shown in Figs. 2 and 5, whereby the said rollers are brought into engagement with the groove 9 of the member 8, locking the said base to said member. The flattened portion 19 being normally inclined, as shown in Figs. 2 and 5, will come in engagement with the ends of the member 8 when said base is forced on to said member, thereby automatically forcing the resilient members toward the base while passing said ends, the said locking rollers then being restored to their normal position by the resiliency of the said members 18, therefore the said resilient members 18 are only mani ulated when removing said base from the rearm. To facilitate the manipulation of the resilient members, each is provided with a milled surface 20 at its free end.

The base 11 at its top is provided with an arcuated dovetail groove 21 disposed transversely to the longitudinal axis of the breech and into which groove fits a similar arcuated dovetail projection 22 of the support 12. The base 11 is also provided with a central bore 23; and the support 12, with a substantially central elongated recess 24. The said bore and recess are in alinement with each other, and both are at the contacting surface of the said support and base. Rotatably mounted in the bore 23 is a plunger 25, the upper portion 26 of which projects into the recess 24. The said portion 26 is provided with a threaded bore 27 engaged by a screw 28 carried by the support 12 transversely to the aXis of the breech and mounted to rotate freely in said support. By rotating the screw 28 in the support 12, the support is translated laterally on the base 11 in the groove 21. The movement of said support on the base is limited by the engagement of the ends of the recess 24: with the sides of the portion 26 of the plunger 25.

The lateral translation of the support on the base by the screw causes the said support to swing on said base laterally in an arc, the center of which is at a (see Fig. l), the said center being the center of curvature of the arcuated groove 21 and projection 22. From the above it will be seen that by turning the screw 28 in either direction the support 12 is swung laterally on the base in a corresponding direction, thereby permitting the adjustment of the telescope 29 carried by the split collar 30. The freedom of movement of the screw 28 in the support 12 is controlled by means of a washer 31 and a screw 32, whereby a self-locking arrangement between the said screw 28 and the plunger 25 is obtained, that is, when the support 12 is to be swung laterally on the base 11 by means of the screw a certain effort is required to overcome the resistance to the movement of said screw and also the frictional resistance between the dovetail projection 22 and the groove 21, and, therefore, the same will remain in said position undisturbed by the vibrations of the firearm.

From the above it will be seen that the essential of my invention is the provision of a telescope mounting whereby the said telescope can be swung laterally about a general center and which mounting can be easily and quickly attached or detached from a member associated with the firearm.

Having thus described my invention, I claim as new and desire. to secure by Letters Patent:

1. In a telescope mounting, a base having means for removably attaching the same to a firearm, said base having an arcuate dovetail groove at the'top thereof and a central bore associated with said groove and perpendicular thereto; a telescope support havcess; and a screw carried by said support and engaging said plunger, whereby said support can be moved laterally in said groove of the base, the movement of said support on the base being limited by said recess in the support.
